This method, based on those of Carolan[2], Carruthers and Oldfield [3], Drago et al. [4] and Kubadinow [5,6], is used for the determination of the contents of potassium and sodium in sugar beet brei after extraction and defecation using lead acetate or aluminium sulphate respectively.
For ecological and health reasons, the defecation using lead acetate should be avoided whenever possible.
